23425	PHP warning in WP_Query::get_posts() when url includes ?page[]	dave1010		"To reproduce:

1. Install WordPress (I cloned from https://github.com/WordPress/WordPress, @ [23391])
2. Go to `http://example.com/?page[]`

Stack trace:

    Warning:  trim() expects parameter 1 to be string, array given in /var/www/projects/wordpress/wp-includes/query.php on line 2024

      8. trim() /var/www/projects/wordpress/wp-includes/query.php:2024


Looks like the query var ""page"" needs sanitizing / casting to string, either with the `trim()` on line 2024 or before."	defect (bug)	closed	normal		Query	1.5.1	normal	duplicate
